METAL WAGON GEAR.

SPECIFICATION forming part of Letters Patent No. 699,642, dated May 13, 1902.

Application filed December 27, 1900. Serial No. 41,299. (No model.)

To all whom it may concern:

Be it known that I, JAMES H.1BAKER, a citizen of the United States,residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have inventedor discovered new and useful Improvements in Metal Wagon- Gear, of which the following is a specification.

In the accompanying drawings,which make part of this specification, Figure I is a side elevation of an axle-arm, axle, sand-board, and braces. Fig. I represents a like View showing rock-bolster, but with a modified sand-board and center connection between the axle and sand-board. Fig. II is a plan View of the hounds and reach, broken away, with the axle and a portion of the axle-arm in horizontal section. Fig. III is a brokenaway detail of one of the hounds. Fig. IV is a section on line a 4. of the hounds. Fig. V is a side elevation of the axle-arm, the axle and bolster being broken off. Fig. V1 is a section on line 8 6 of Fig. V. Fig. VII is a section on line 7 7 of Fig. V. Fig. VIII is a section on line 8 8, Fig. V; Fig. IX, a section on line 9 9 of Fig. V, and Fig. X a section on line 10 10 of Fig. V. Fig. XI is a side elevati'on, broken away, of axle-arm and axle where a wooden bolster is employed. Fig. XII is a cross-section through said wooden bolster. Fig. XIII is a plan view of the rockbolster broken away in the center and at the ends.

My invention, generally stated, relates to improvements in wagongears, particularly such as are used for heavy work and of the form denominated farm-wagons.

The object of the invention is to make them more simple and substantial and to reduce the cost of manufacture.

In carrying out my invention I make the difierent parts principally of metal. The parts with which I am specifically concerned are the axle-arm, the axletree, the bolsters, and the reach-brackets at the hound ends and center piece.

The axle-arm I make with the usual spindle 2, dividing and spreading the arm, running one branch 2 back to receive the axle 3 and running the other branch 2 upward to receive the projecting connection 4 from the bolster 5. These dividing branches I make with vertical webs provided with flanges C C, as seen in Figs. V and VI. The axletree 3, which is made of angle-iron, is bound edgewise between two of these flanges, (see Fig. V111,) and this construction adds very materially to the strength of the joints between the axletree and the axle-arm. The same form of construction is shown in Fig. I, where the sand-board 6, instead of the bolster, is joined to the axle-arm. The flanges on these branches are made narrower and thinner as they approach the ends of the arm, so

as to save metal and avoid too much rigidity where the axletree and sand-board or bolster join these parts and also to give room for a sufficiently large hole 2", wherein to enter the hound 7. My object is to join the hound to the axle in such a substantial way that all the vibration of the hound shall be taken up in that part of the hound between the axle and its point of contact with the tongue or reach. It is also important that the hound should be joined to the axle or axle-arm at a point as near the wheels as possible to avoid bracing from axle to hound, as is usually done. This I accomplish by my construction. The construction on the ends of the hounds where they join the axle may be formed on the end and integral with the hounds or may be formed in a separate piece. This separate construction would be the one used where it was desirable to use a wooden hound. The arm, with its branches, I preferto make bydrop-forging, although it may be made of a steel casting by methods commonlyknown; butwhether made by either of the above methods it maybe made to carry a wooden bolster 5, such as shown in Figs. XI and XII; but in such case the upward projection 2" would be channelshaped to receive said wooden bolster. In all cases the prime object is to devise an axle arm or spindle which maybe securely united to a metallic axletree and bolster or sand board in a simple manner, and in case of a rupture or break of the arm or its adjacent parts the means used in connecting them together can be readily removed and the parts separated and a new member substituted, thereby constituting a detachable and removable axle-arm.

In Fig. I, I have shown diagonal cross-section braces 8 8, uniting and strengthening the axle and bolster or sand-board. In the same figure I show a center piece 9, consist ing simply of two flat bars 9 9 riveted to each other and one riveted to a cross-brace 8.

The hound ends or tongue and reach brackand also rib them at-ll Figs. III and IV, on

the inside of the bracket, thus making when the two are combined a box-fastening for the tongue or reach. This box can be widened or narrowed at will by differing the lengths of the bolt 11 or in case of the reach of the straps 11 11, which would take the place of a bolt, as shown in Fig. II. I strengthen these outside flanges byinserting webs 11 ll The rock-bolster shown in Fig. I and Fig. XIII, I construct with a center piece 12. This center piece has a vertical web 12 connecting top flange 12 and bottom flange 12 Between flanges 12 and 12 and extending transversely of the bolster and of said flanges are webs 12. On the top of flange 12 is the top horizontal member of the bolster, and secured to the bottom flange 12" are the lower members of the bolster, only the right-hand These members are connected by vertical struts, which have integral projections, to which are fastened the diagonal ties 12", the innermost tie being socured to a part of the web 12. The bottom member is seated against the shoulder projection or abutting piece 2, which has a flange 12 extending over and closed down on the end of said member. This gives a light, substantial, and strong construction. As the top and bottom plates of the rockbolster are narrower at their ends, the two bottom plates may be cut from the side of the top plate from stock of sufficient width by reversing tapers, so as to lose very little metal. When using this construction for a rear axle,the center piece would have top and bottom reversed. Where desirable my improved center piece can be used with channels or Ts by simply changing the parts where they would unite with the main members.

Having described my invention, I claim- 1. In combination, a wagon running-gear having an axletree, a bolster or sand-board, and an axle-arm, the latter having two members each provided with a vertical web reinforced by flanges, between which the axletree and the bolster or sand-board are secured.

2. The combination of an axletree, a bolster and an axle arm divided into two branches, one branch flanged to receive the axletree and the other branch channel-shaped at its upper end to receive the bolster.

3. A wagon rock-bolster composed of a top and bottom member, a central vertical strengthening-plate between said members and struts tied to said plate and each other between said top and bottom members.

4:. An axle-arm provided with flanges between which are secured both the axletree and projections from the bolster or sandboard, said axle-arm perforated transversely; whereby the end of a hound or hound-bracket can be inserted in and secured to said axle.

5. In a wagon rock-bolster, a central vertical member, reinforced by upper and lower flanges a horizontal top member and two short lower horizontal members, said lower members secured to the lower flanged portion of said vertical member and extending outwardly therefrom.

6. In a wagon rock-bolster, a central vertical flanged member, projections from said member whereby ties can be secured thereto, shoulder projections on said member against which the bottom members of said bolster abut.

7. A wagon rock-bolster, consisting of upper and lower plates united by struts and ties, said struts having integral projections extending therefrom and said ties being interposed between and secured to said projections. 7

8. In a wagon rock-bolster, a central vertical flanged member, a shoulder projection on said member against which a bottom member of said bolster abuts.

9. In combination an aXletree, a sandboard or .bolster and an axle-arm having one of its members composed of a vertical web reinforced by transverse flanges, the axletree having one of its ends secured between the flanges of said member and a second member composed of a vertical web reinforced by flanges whereby a projection from the bolster or sand-board can be secured between said flanges. 4

10. An axletree, a sand-board or bolster, and an axle-arm integrally composed of a spindle, a member to which the axletree is secured and a second member to which the sand-board or bolster is secured.
